This is still related with my previous questions, VBA: How to display an error message just like the standard error message which has a “Debug” button?

Now, I successfully make the current cursor in VBE jump to a particular procedure in VBE. I used Application.Goto to achieve this. However, what actually I want is to make the current cursor in VBE jump to the line where the last error occured. I suspected there should be something useful for this purpose in Application.VBE object but didn't know which?

Solving this also means satisfying my previous question entirely. Any hints or even dirty tricks?

Continued from your previous question :)

I suppose you are already using line numbering (as answered in the previous question).

So, modify your error handling routine to something like:

Sub aa()
Dim zz As Long

10:     On Error GoTo ErrorHandler
20:     DivisionByZero = 1 / 0
30:     Exit Sub
ErrorHandler:
41:  If Err.Number <> 0 Then
42:     Msg = "Error # " & Str(Err.Number) & " was generated by " _
         & Err.Source & Chr(13) & "Error Line: " & Erl & Chr(13) & Err.Description
43:     MsgBox Msg, , "Error", Err.HelpFile, Err.HelpContext
        zz = CodeFind("", "", Str(Erl), 0)
44:     End If
50:     Resume Next
End Sub

Now for the CodeFind() thing. I found it here (at the bottom, the last one), but had to modify it a bit, so I'm posting a lot of code ... sorry.

Insert this code in a new module and be sure you have the reference to "Microsoft Visual Basic For Applications Extensibility 5.3" checked, and the project is not protected. In doubt see here.

HTH!

Here is the code

 Option Explicit
 '---------------------------------------------------------------------------------------
 ' Procedure : CodeFind

I vote up first, acceptance will follow after I make a test. :-)

@vantomex Good luck!
belisarius
@belisarius, well, it seems I start to think that you're one of the VBA superheroes. Thank you very much. It works perfect as expected. BTW, I'm OK for even a thousand line of codes (hopefully people too), sorry for wasting your time. :-)
Vantomex
@Vantomex Glad to know it worked for you. The real credit is for the original author,although he intended to use the code for other purposes. I just customized a few lines. Also note that answering this kind of questions is by no means a waste of time as I also learn a lot in the process!
